I now have a solid set of sources. Here is a comprehensive answer:
Patellar Tendonitis (Patellar Tendinopathy) - Treatment
Also called "jumper's knee," patellar tendinopathy results from chronic repetitive loading (running, jumping) causing microtears in the tendon and an inflammatory cascade. Here is how it is managed across the spectrum of severity.
1. Diagnosis Essentials
- Pain at the inferior pole of the patella, worsened by activity (stairs, squatting, jumping)
- Tenderness on direct palpation of the tendon
- Plain X-rays: rule out avulsion fracture or patella alta
- MRI or ultrasound: confirm diagnosis in uncertain cases
- Red flags - palpable defect, inability to straight-leg raise - suggest rupture, not tendinopathy
2. Conservative Management (First-Line)
Relative Rest
- Reduce aggravating activity (not complete immobilization)
- Offload the tendon during the acute/painful phase
NSAIDs
- Short-term use to reduce pain and inflammation
- Useful in the early, symptomatic phase
Physical Therapy - Exercise Rehabilitation (Cornerstone)
This is the most important and evidence-based treatment:
| Exercise Type | Role | Evidence |
|---|---|---|
| Eccentric loading (e.g., decline squat, single-leg squat lowering) | Best for long-term pain reduction and functional improvement | Grade A (multiple RCTs) |
| Isometric loading (e.g., wall sits, leg press holds) | Best for short-term/in-season pain relief, especially during sport | Grade A |
| Concentric-eccentric | Progressive strengthening for later rehab phases | Moderate evidence |
A 2025 Cochrane review (PMID 40421598) found strengthening exercise produces meaningful pain reduction vs. no treatment, and a 2024 systematic review (PMID 40666246) confirmed that eccentric exercises are superior for long-term outcomes while isometric exercises give better short-term pain relief during athletic activity.
Classic eccentric protocol (Alfredson):
- Decline squat: 3 sets x 15 reps, twice daily, 12 weeks
- Progress by adding load (holding dumbbells) once pain-free
Stretching
- Quadriceps and hamstring flexibility work - adjunct to strengthening
3. Adjunct / Intermediate Therapies
| Therapy | Notes |
|---|---|
| Patellar tendon strap/brace | Offloads the tendon insertion; symptom relief during sport |
| Dry needling | Promising for pain reduction; high-quality trials show benefit (Grade A, 1B evidence) |
| PRP (Platelet-Rich Plasma) | Increasingly used; evidence emerging but not yet definitive |
| Shockwave therapy (ESWT) | Moderate evidence for refractory cases; stimulates tendon remodeling |
| Pulsed ultrasound / Transverse friction massage | Evidence is weak vs. exercise |
Steroid (glucocorticoid) injection: NOT recommended. Rosen's Emergency Medicine explicitly states there is no role for steroid injection in patellar tendinopathy. Cochrane data also shows it is not superior to exercise.
4. Surgical Treatment (Refractory Cases)
Reserved for patients who fail 3-6 months of conservative therapy:
- Arthroscopic or open debridement of the tendon (removal of degenerative tissue)
- Percutaneous needle tenotomy (ultrasound-guided)
- Tendon scraping / longitudinal tenotomy
A 2025 systematic review (PMID 40215473) of 485 patients found:
- VISA-P scores improved by ~40 points post-surgery
- VAS pain scores dropped by 6.1 points
- Return-to-play rate: 87%
Surgical results are generally good, but most surgeons still consider it a last resort.
5. Return to Sport - Timeline (General Guide)
| Phase | Timeframe | Goals |
|---|---|---|
| Acute | Weeks 1-2 | Pain control, relative rest, isometrics |
| Sub-acute | Weeks 2-6 | Progressive eccentric loading, flexibility |
| Strengthening | Weeks 6-12 | Heavy slow resistance, sport-specific conditioning |
| Return to sport | 3-6 months | Full load tolerance, pain-free throughout |
Key Takeaways
- Eccentric strengthening is the backbone of treatment - start it early and do it consistently
- Isometric holds are especially useful for in-season athletes who cannot rest
- No steroids - they do not help and may worsen tendon structure
- Surgery works well when conservative care fails (~87% return to sport)

Clean clinical illustration style.
This diagram illustrates the key anatomy of patellar tendonitis (jumper's knee):
- Patella - the kneecap, sitting at the top of the tendon
- Patellar tendon - connects the patella to the tibial tuberosity; the site of injury
- Tibial tuberosity - the bony prominence on the shin where the tendon inserts
- Inflammation zone - typically at the inferior pole of the patella (where the tendon originates)
- Microtears - microscopic damage within the tendon from repetitive loading, which drives the chronic pain cycle

This illustrates key physiotherapy approaches for patellar tendonitis rehabilitation:
- Decline squat (eccentric loading) - the gold-standard exercise; performed on a slanted board to maximally load the patellar tendon during the lowering phase
- Isometric holds - static quad contractions (e.g., wall sits) for short-term pain relief, especially useful during the in-season period
- Therapist-guided manual therapy - soft tissue work and guided joint mobilization
- Progressive strengthening - advancing from bodyweight to weighted exercises over 6-12 weeks
Consistent physiotherapy for 3-6 months is the cornerstone of full recovery and return to sport.
